    • A surface antenna with a single radiation element, which comprises (a) a power source with first and second poles; (b) a phase shifting element, inserted to the path of one of the poles of the power source in such a manner that the phase shifting device shifts the phase of a first signal propagating through said pole such that the shifted phase of the first signal will be essentially identical to the phase of a second signal propagating through the other pole. The shifted first signal is added to the second signal with essentially the same phase of second signal, whenever both poles are connected together to form a single-wire, through which the resulting added signal propagates. Alternatively, the antenna may include two phase shifting elements, coupled to each of the poles of said power source in such a manner that one of the two phase shifting elements shifts the phase of a first signal propagating through the first pole while the other phase shifting element shifts the phase of a second signal propagating through the second pole such that the shifted phases of both signals will be essentially identical, and such that the shifted signals are added with essentially the same phase, whenever both poles are connected together to form a single-wire, through which the resulting added signal propagates; (c) a radiation element, in the form of a flat radiation layer that may be adapted to match a variety of surfaces, for receiving the added signal, wherein the added signal may be spilt into two or more wire lines with identical or different lengths.
    • 具有单个辐射元件的表面天线,其包括(a)具有第一和第二极的电源; (b)相移元件,其以这样的方式插入到电源的一个极的路径中,使得相移装置移动通过所述极传播的第一信号的相位,使得第一信号的移位相位 将基本上与通过另一极传播的第二信号的相位相同。 每当两个极连接在一起以形成单线时,移位的第一信号被加到具有基本上相同的第二信号相位的第二信号上,所产生的附加信号通过其传播。 或者,天线可以包括两个相移元件,其以这样的方式耦合到所述电源的每个极,使得两个移相元件之一移动通过第一极传播的第一信号的相位,而另一相移 元件移动通过第二极传播的第二信号的相位,使得两个信号的移位相位将基本相同,并且使得移位的信号以基本上相同的相位相加,每当两个极连接在一起以形成单个 所产生的附加信号通过其传播; (c)可以适于匹配各种表面的平坦辐射层形式的辐射元件,用于接收所添加的信号,其中所附加的信号可能溢出到具有相同或不同长度的两条或更多条线路中 。
